Is this alternate solar system possible?

[Spaceception]

Here's an updated moon for @silversliver:

Loki:

0.069 moons mass

Loki is a small moon, a little over 5x the mass of ceres, and 7x the radii, and almost 70% nitrogen ice (The rest being rock), because of it's small orbit (1/3 the Earth moon system) It's extremely cold (-266 c), however, it has a thin atm of nitrogen about half as thick as Mars' (OTL) constantly being replenished by  nitrogen chryovolcanoes all over the moon, suggesting that there's a large ocean of nitrogen under the surface, and perhaps exotic life.

And a second moon for @ChrisSpace:

Erebus:

Named for the Greek god of shadows, it has a well picked name, as the moon is covered in a substance much like soot, absorbing 98% of the almost nonexistent light hitting it, it's also about the size/mass of Ceres (Slightly larger) with a very wide 1 year long orbit, and an average temp is just 2 c above absolute zero, making it almost impossible to detect, however, the main reason it was possible to detect it in the first place, was because of the wide (Wide for Erebus anyway) system of rings surrounding it, which were though to have come from several Asteroid moons that got too close.

What do you guys think?

 

Also, @fredinno I'm going to make the second moon for silversliver (And second one for you) later today.

I like your idea for Erebus. Also, after a bit of simulating I found a way to include Planet Nine into this solar system without removing anything. I'll update the front post soon-ish.

I like this.

Now an update on things and a question.

FINALLY tomorrow I should have enough time to finalize Mars and Bellona.

Question is: do you imagine the surface of the alternate Mars more Earth-like or more Mars(OTL)-like?

I imagine it as Mars OTL, but with much larger ice caps.

with less petrochlorates, also those ice caps might be problematic due to decreased albedo

I imagine it to look like those pictures of what a 'terraformed' Mars would look like. Same terrain, but it's all covered in either forests, grasslands, snow or water.

And Mars (and Bellona)

Mars is supposed to be a lot colder- almost like ice age Earth, but slightly warmer.

And also, if Bellona was so close to have stress stripes, that'd probably too close, as it means that it would collide in a few hundred million years (possibly faster, due to being a larger moon than Phobos).

 

So, bad idea, really.

The blow up of Alderaan was supposed to be the funny part .

Here's an updated moon for @silversliver:

Loki:

0.069 moons mass

Loki is a small moon, a little over 5x the mass of ceres, and 7x the radii, and almost 70% ammonia ice (The rest being rock), because of it's small orbit (1/3 the Earth moon system) It's extremely cold (-220 c), however, it has a thin atm of ammonia about half as thick as Mars' (OTL) constantly being replenished by  ammonia chryovolcanoes all over the moon, suggesting that there's a large ocean of ammonia under the surface, and perhaps exotic life.

Named for the Greek god of shadows, it has a well picked name, as the moon is covered in a substance much like soot, absorbing 98% of the almost nonexistent light hitting it, it's also about the size/mass of Ceres (Slightly larger) with a very wide almost polar orbit, and an average temp is just 2 c above absolute zero, making it almost impossible to detect, however, the main reason it was possible to detect it in the first place, was because of the wide (Wide for Erebus anyway) system of rings surrounding it, which were though to have come from several Asteroid moons that got too close.

Remember, these moons must be close in (except for ChrisSpace, which would be created under different circumstances- presumably like a star, but much smaller in scale) they were all slung out, so any moons would be captured, close in, or possibly not there at all.

 

Don't worry, I'll work with the Gs.

Honestly, I was thinking defining the Planets themselves, not the moons, but hey, I'll deal with what I've got.

Loki:https://en.m.wikipedia.org/wiki/Coreless_planet

SilverSilver is a coreless planet from a water-rich nebula, made from a location farther from its host star (before being slung out). If it's moon is formed next to SilverSilver, it must have a similar composition- making the moon unlikely. Also, the ambient temperature of interstellar space around 2-3 K, or -270 C. Only problem with Tidal heating for SilverSilver is that it lacks a large host body, or another large moon to gravitationally interact with to have a liquid ammonia underground ocean. Liquid Nitrogen might work, but you at least need one large moon to resonate with to increase tidal heating for that. 

 

Erebus:

Polar orbits are unlikely, but surprisingly possible. http://physics.stackexchange.com/questions/76181/when-can-a-natural-satellite-be-in-polar-orbit-around-its-primary Choose one please, then we can start working out likelihoods and mods to the primary itself.

 

And a ringed moon AND polar orbit sounds too much unlikeliness for one moon. Please choose one.

 

Overall though, you did pretty good. Good job.

Next will be the moons of the gas giants. Hilarity may ensue.

A) Yes.

B)Yes, except for the water, I had to add more because I tried to put less water and it was not showing up.

1)I can put only a surface map so or water or ice.

2) The "stress" stripes were created by the random terrain generator.

For @silversliver

Eros:

Eris is named for the Greek god of Chaos, this moon has an elliptical orbit, and a wild axis of rotation, it's not very big, Only 1.2x the mass of Ceres, and 1.4x the radii of Ceres, but it's orbit/size makes it possible for Loki to have stable liquid nitrogen oceans, there's a few surface features, such as "The belt" which is a ridge that spans 1/2 the moon at the equator, much like Iapetus. It's made up of mostly water ice and rock, but additionally, some metals as well, there's no atmosphere, and the average temperature is 1 c above absolute zero.

? g

For @fredinno

Apollo:

Apollo is named for the Greek god of Art, due to it's unusual but beautiful surface features, such as on the north pole, there's curved streaks of red colored "stripes" that all follow the same path from the north pole, to the southern hemisphere, it's made of mostly rock, with an abundance of metals, such as Iron, which is thought to be in the red stripes as Iron oxide, it has a mas of 1.3 moons, and a radii of 1.6 moons, as well as a wide but elliptical orbit, both Apollo and Mustafar tidally heat each other along with Fredinnus, although Apollo isn't as tidally heated as Mustafar, it's heated enough that a few small volcanoes have given a thin atmosphere that is 3x the thickness of Mars (OTL), making the temperature -210-40 c.

So what do you guys think about these moons?

I know about Eris, but I just heard of Apollo, what does it matter anyway? There's no Eris or Apollo in this solar system, so it's free game.

Aside from that, what do you think about them?

How about an ice giant that froze and it got a surface of methane and nitrogen ice with hydrogen lakes?

Hmmmm, I'll work on it later.

[Spaceception]

Let's get crackin' on that Ice giant now:

Amphitrite:

Amphitrite is named for the Greek goddess of the sea (And is Poseidon's wife), because it's covered in a global ocean of liquid Nitrogen The planet is 8.6 Earth masses, and 3.2 Earth radii, putting it near the border of "Super-Earth" and " Mini-Neptune", and has an atmosphere 23x the density of Earth's, and is made primarily of Hydrogen, Methane, and Nitrogen, with trace amounts of Argon, giving it a very dim blue color, it's temperature is -200 c, and it has a small system of rings, about 10 km wide, thought to have come from a few small Asteroids about 10 million years ago, the planet has a mostly circular orbit, extremely far from the sun. 1780-1920 AU

No moon

What do you think @Findthepin1 ?

Well, at 2300-2590 AU there isn't enough heat to give it methane oceans. I meant hydrogen lakes, and the ground being methane ice. Other than that, it's great.

Heat? It's ~10 c colder than Titan, and it has Methane seas.

Oh, you mean Hydrogen seas? I'll switch some stuff around.
